Answer 1

1. All Gruner Corporation employees will be invited to the holiday (celebration) scheduled for next Friday .
holiday celebration = 节日庆祝活动
英语常用名词来做形容词
这里 holiday 是形容词， “节日的”
其他名词作形容的用法包括
coffee shop
music store
customer complaint
telephone message
computer program

等等

2. effective 可接介词 in 和 for
effective in sth 是固定用法
in 是这个短语的固定介词
effective in attracting customers
的意思是
对吸引顾客有效力。
举个类似例句：
Keeping calm can often be effective in diffusing tense confrontations

Answer 2

选celebraion，庆典。其他意思不对。A，管理。B，出席。D，情况。
be effective in doing sth. 做什么有效。
